Minimal Clinically Important Difference and Patient-Acceptable Symptom State in Orthopaedic Spine Surgery: A Review. Issue 4 (18th April 2023) - Adindu, Ebubechi K.
Abstract : » Minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) are both metrics at interpreting patient-reported outcome measures (PROMs). » MCID values tend to vary significantly depending on the baseline pain and function in both acute and chronic symptom states while PASS thresholds are more stable. » MCID values are more easily attainable than PASS thresholds. » Although PASS is more relevant to the patient, it should continue to be used in tandem with MCID when interpreting PROM data.
